Definition of the
error
Ways to fix the error
Voltmeter Fault
Flashing red 1 time
Meter fault
a) Unplug the J1772 connector
and reboot the charger.
b) If the fault persists, contact
EVIQO technical support.
Control Pilot Fault
Flashing red 2
times
3 seconds interval
Charging guide
abnormal
a) Unplug the J1772 connector
and reboot the charger.
b) Make sure the CP (Control
Pilot) line is fixed in the right
place.
c) Check if the CP line in the
connector runs an electrical
short-circuit or open circuit.
d) The device will recover
automatically when the problem
is solved. Reconnect the charger
to the EV car for further normal
use.
Undervoltage
Protection
Flashing red 3
times
3 seconds interval
UVP (Under Voltage
Protection) Fault.
UVP Fault is triggered
when the input voltage
is below 90%
(208V*0.9=187V) of
rated voltage.
a) Unplug the J1772 connector.
b) The device will recover
automatically when the input
voltage stabilizes within the
required range.
Overvoltage
Protection
Flashing red 4
times
3 seconds interval
OVP (Over Voltage
Protection) Fault.
OVP Fault is triggered
when the input voltage
is over 110%
(240V*1.1=264V) of
rated voltage.
a) Unplug the J1772 connector.
b) The device will recover
automatically when the input
voltage stabilizes within the
required range.
Overheat Protection
Activated
Flashing red 5
times
3 seconds interval
OTP (Over Temperature
Protection) Fault.
OTP Fault is triggered
when the temperature of
the charger interior is
over 185°F (85°C).
a) Unplug the J1772 connector.
b) The device will recover
automatically when the
temperature turns lower than
185°F (85°C).
c) If the problem persists, turn off
the power and carefully check if
the thermistor on the PCB works.
